seacost mountains totals
7th grade 70 40 110
8th grade 90 110 200
totals 160 150 310
determine the relative frequency of the percent of 7th grades who prefer mounatains. round the percentage to the nearest tenth
To determine the relative frequency of 7th graders who prefer mountains, you divide the number of 7th graders who prefer mountains by the total number of students surveyed:
Relative Frequency = (Number of 7th graders who prefer mountains / Total number of students surveyed) * 100
Relative Frequency = (40 / 310) * 100
Relative Frequency = 0.129 * 100
Relative Frequency = 12.9%
Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 12.9%.
that wrong seacost goes to the first number and down then mountains goes to the seconed number and down and totals goes to the third number and down try agin
I apologize for the error. Let's correct that:
To determine the relative frequency of 7th graders who prefer mountains, you divide the number of 7th graders who prefer mountains by the total number of 7th graders:
Relative Frequency = (Number of 7th graders who prefer mountains / Total number of 7th graders) * 100
Relative Frequency = (40 / 110) * 100
Relative Frequency = 0.3636 * 100
Relative Frequency = 36.4%
Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 36.4%.
